Hyperalgesia is defined as "An increased sensitivity to pain, which may be caused by damage to nociceptors or peripheral nerves". It is divided into 2 types, primary and secondary. Primary hyperalgesia - pain and sensitivity in the damaged tissues. Secondary hyperalgesia - pain and sensitivity that occurs in area around the damaged tissues.

Hyperalgesia is divided into two categories: primary and secondary. Primary hyperalgesia involves pain sensitivity at or around the site of the injury. Secondary hyperalgesia occurs when the pain spreads to other areas of the body. Opioid-induced hyperalgesia is a specific type of hyperalgesia that can occur as a result of taking opioid medications.

Some individuals develop large areas of secondary hyperalgesia (high-sensitization responders), while others develop small areas (low-sensitization responders).

17 In the present study, secondary hyperalgesia was detected at a very early stage, that is, from the 3rd day after nerve injury, almost simultaneously with the primary hyperalgesia. Experiment 1: Primary and Secondary Hyperalgesia Testing After Plantar Incision. Before incision, catheterized rats were acclimated to the testing room and testing apparatus (i.e., individual plexiglass compartments measuring 26 × 11 × 20 cm with 12 × 12 mm mesh floors) for 30 min on each of three sequential days. Solution for Secondary hyperalgesia is : a.Outside of the lesion site b.

When afferent neurons are involved with central sensitization, secondary hyperalgesia can appear. Secondary hyperalgesia is an increased sensitivity to 

Secondary are hyperalgesias occurring outside such an area. (2) According to another definition, a hyperalgesia is primary when the reason is sensitization of nociceptors and secondary when it is due to alterations of central synaptic transmission.

robotic arm equipped with a load cell and a pinprick probe was proposed for automatic measurements of different sensory modalities (threshold, hyperalgesia,

Secondary hyperalgesia refers to the sensitization that occurs because of changes in spinal cord processing. For example, through a process of central sensitization, the firing of dorsal horn nociceptors can change dramatically in the setting of injury (produced by either tissue or nerve damage).
